Description
Technical field
The present invention relates to a kind of air valve of dry-running.
Background technique
For needing large opening cross-section to amass to the air valve in combustion chambers of internal combustion engines supplying gaseous fuel, enough vaporized fuel can be introduced in cylinder chamber in short operational opening time.Such air valve is opened by electromagnet usually, and wherein electromagnet must can realize enough strokes and must apply enough magnetic force, can supply required gas flow in short opening time.In addition, the opening and closing time short is as far as possible Worth Expecting, so that air valve can become long as far as possible the wide-open time in bent axle circulation.One of internal-combustion engine with crankshaft angular displacement statement for continuing 720 ° and for the bent axle cycle period continuing 360 ° two-cycle engine four stroke engine, vaporized fuel to be supplied in the firing chamber of internal-combustion engine once.For this reason, usually only provide very short time available, therefore air valve very rapidly must open and close and must have enough cross-sectional flow areas, can introduce required gas flow within the operational time.Typically in big-block engine, the crankshaft angles of 90 ° of whole bent axle circulation is available for introducing vaporized fuel.Air valve must to be opened in this discharge time, supplying gaseous fuel is closed gas check valve again to firing chamber.Therefore according to the difference of rotating speed, this is only provided to several milliseconds, typically 10-25ms is available.Therefore air valve must very rapidly switch and must have large opening cross-section and amass, can supply enough vaporized fuel within the time that this is short.But particularly in the atmos-valve of big-block engine, these require to be difficult to realize.
Therefore, air valve usually has the valve element with multiple flow channel of plate-like similarly with constrictor valve, and wherein valve component seal ground and valve seat act synergistically, and this valve seat has multiple flow channel equally.Such valve element typically comprises multiple concentric ring, and these concentric rings are interconnected by the radial lath be distributed in circumferentially.Difference between air valve and constrictor valve is, constrictor valve is automatic, and air valve is such as by magnet control that is by active (aktiv) ground switch.The valve element of constrictor valve is stopped on valve limiter and whole ground abuts in there due to the pressure of effect, and the valve element of air valve must be stopped on blocked part.In constrictor valve, intermediate pin is configured with diameter little as far as possible, available flow surface can be kept large as far as possible.Because also act on breaking force, such as magnetic force on the valve element of air valve, so produce flexural stress when abutting on blocked part in valve element, valve element can be caused obviously bending for this flexural stress and such as gear leans against on electromagnet or gas is hindered by the percolation of valve.Particularly when breaking force medially acts on valve element, such as in the mode of execution with valve element central pin fixed thereon, and when blocked part is arranged on radially outer, just always this situation.Therefore, the component bent correspondingly must determine size significantly, but this means again larger quality and slower opening and closing time.Another kind of possibility is, is chosen to by residual gap so big, although so that bending gear of valve element lean against on electromagnet.But large air gap reduces effective magnetic force, this or reduce the pressure reduction that can connect and the opening speed that can reach or determine larger electromagnet, but this is undesirable both ways.
The example of this air valve is such as open at US5398724A.The valve element of this air valve is fixed on armature by central pin.Being provided with circumferentially distributing for receiving helical spring space at valve element.Helical spring other end is arranged in the space on spring seat, and this spring seat also forms the blocked part for valve element.These springs produce closing forces on the one hand, lead on the other hand to valve element.Because be arranged on radially outer for the blocked part of valve element, so produce undesirable flexural stress in valve element.
In compressor, usually always be there is oil by the medium (such as air) that compresses, from the lubrication of compressor, therefore the movable part of constrictor valve is lubricated equally together.In such " lubricated " constrictor valve, valve element can be directed on the intermediate pin of central authorities.But in the constrictor valve of dry-running that is in the valve not having this intrinsic lubrication, valve element due to friction and the wearing and tearing associated therewith and temperature rising can not medially be directed on intermediate pin.Therefore the constrictor valve being only diverted the dry-running of device guiding is known, wherein, a part for valve element is kept regularly by position and the part that this position is fixed is connected via the active part of so-called steering arm with valve element, and therefore this active part is rubbed and lead less.
In air valve, the air valve of also unknown dry-running so far, wherein valve element is directed in guiding device.The valve element be directed to such as by EP 425 327 B1 for lubrication air valve be known, wherein the oiling agent be under pressure is supplied to valve.But this air valve does not have the valve element with multiple percolation passage of plate-like, but valve element is here made up of the armature of circle, and this armature is connected with vertical piston.The end face deviating from armature of piston forms sealing surface at this, and the end face seal ground of sealing face and valve seat acts synergistically.At this, piston is directed in the cylindrical port of radially outer at air valve.Due to this layout, there is not the bending problem of valve element here.
Above-mentioned US 5398724A also discloses a kind of air valve of dry-running, and wherein, the guiding of valve element realizes via helical spring and is not via guide surface.
Summary of the invention
Now, the object of the invention is to, provide a kind of air valve of dry-running, the problem substantially avoiding valve element to bend in this air valve and however still can obtain high opening speed.
Described object is by realizing like this according to air valve of the present invention, namely, the valve element with multiple percolation passage of plate-like is comprised according to the air valve of dry-running of the present invention, this valve element and valve base sealing ground act synergistically, wherein valve element is connected with armature, this armature and the electromagnet be arranged in air valve act synergistically, valve element is guided to by inner radial by this way, supportedly arrange, namely on valve element, the guiding area with the first central void is provided with in inner radial, the inner peripheral surface of this first central void forms guide surface, and valve element to push away with the first central void on the guide finger that is contained in and is medially arranged in air valve and can be axially movably on guide finger, support with being directed to, armature is connected with valve element on guiding area, and the blocked part be provided with in air valve for valve element, this blocked part and guiding area act synergistically, middleware is provided with in air valve, the first end of electromagnet and spring is set in this middleware in the second central void, this electromagnet and spring and valve element act synergistically, be provided with baffle ring, the second end of described spring is set in this baffle ring, described baffle ring directly or via space washer abuts on valve element vertically.Because armature and blocked part are at the point of action be positioned on the guiding area of inner radial of valve element, significantly reduce possible the bending of valve element and armature, therefore each component can be configured to not huger, and this means again the quality of less motion and higher opening speed.Meanwhile, residual gap can be kept very little by this mode of execution, therefore can connect large magnetic force and thus higher pressure reduction, particularly there is no pressure compensation ground, and better opening speed further can be obtained.
When being provided with middleware in air valve, can axially movably guide in this middleware, when being supportedly provided with adjusting element, wherein adjusting element to be connected with adjusting nut via screw thread and to arrange the first end of electromagnet and spring in central void in adjusting element on an axial end portion, this electromagnet and spring and valve element act synergistically, can by the stroke of very simple mode adjusting air valve, wherein adjusting element moves axially via adjusting nut.
In order to stroke of regulating valve more accurately can be realized, belleville spring can be provided with vertically between middleware and adjusting element, this belleville spring bias adjustment part, to compensate the axial clearance that may exist.
One baffle ring vertically directly or abut on valve element via space washer, this baffle ring prevent valve element when opening due to gear by and damaged.When being additionally provided with space washer between valve element and baffle ring, very simply and accurately residual gap can be regulated.
In order to reduce the surface friction drag between guide finger and valve element, circumferential groove can be provided with on the guide section of guide finger, in described circumferential groove, load slip ring.Therefore opening speed can be improved further.Advantageously, between the bottom and slip ring of circumferential groove, O shape circle is provided with, so that tensioning slip ring and obtain leading more accurately.
When being provided with a space in armature, when the volume between armature with electromagnet is communicated with ventilation volume by this space, still can further improve the opening speed that can reach.
In order to improve the Security that anti-air-stopping valve leaks, air valve can be configured to double-walled.
But the air valve of dry-running also has another problem, particularly for absolutely dry gas, such as, occur when gas evaporates (such as oil tanker) from liquid phase.Because absolutely dry gas does not have lubrication, so when switch because impact stress often cold welding occurs between valve element and valve seat, this can damage the parts of air valve or air valve.Can specify to eliminate this problem, valve element and valve seat are by different materials, preferably by different metal manufactures.When valve seat be formed from steel and valve element by aluminium, may make with the aluminium of anodized coating time, obtain a kind of particularly advantageous combination of materials.But the plastics manufacture that valve element also can be strengthened by suitable plastics or fiber.
Accompanying drawing explanation
To illustrate but the Fig. 1 not limiting Advantageous embodiments illustrates the present invention referring to exemplary, this illustrates the sectional view according to air valve of the present invention.
Embodiment
As shown in FIG. 1, comprise housing 3 according to air valve 1 of the present invention, in this housing, be provided with a middleware 9.An axial end portion of air valve 1 is provided with a valve seat 10, and therefore this valve seat forms the gas outlet of air valve 1 simultaneously.Valve seat can be a part for housing 3.Here, another relative axial end portion of air valve 1 is provided with gas inlet.Here the air valve 1 shown in is therefore by axially percolation.But it is natural it is also possible that gas also can radially supply at the suitable position in housing 3.
An adjusting element 8 is provided with in middleware 9.Adjusting element 8 this be directed in the space 13 of middleware 9 ground, supportedly arrange and remained on by the screw thread 14 of adjusting nut 12 deviate from valve seat 10 axial end portion on.Adjusting nut 12 abuts on the axial end portion of middleware 9 vertically at this.Adjusting element 8 moves axially by the rotation of adjusting nut 12 thus, so that can stroke of regulating valve simply, as further below more detail subsequently.Also a belleville spring 25 can be provided with vertically, this belleville spring bias adjustment part 8, to compensate the axial clearance that may exist and stroke of regulating valve more accurately can be realized between middleware 9 and adjusting element 8.
At adjusting element 8 towards in the axial end portion of valve seat 10, in central void 11, be provided with electromagnet 5 and spring 6, be helical spring here, this electromagnet and spring act synergistically with valve element 2 as explained below.At this, helical spring 6 is radially arranged on outside electromagnet 5, and therefore helical spring 6 can be specified to size more greatly and stronger not by the available structure space restriction in electromagnet thus, and this can realize higher elastic force.As shown in FIG. 1, can realize via the attachment plug 15 in housing 3 with via the space in middleware 9 for electromagnet 5 supplies electric current.
At valve seat 10 with being provided with a valve element 2 between electromagnet 5 and the adjusting element 8 of helical spring 6.Valve element 2 be configured to plate-like, with being positioned at the guiding area 16 of inner radial and being positioned at the percolation region 17 with multiple percolation passage of radially outer.Percolation region 17 such as can be configured to multiple concentric ring, and these concentric rings are interconnected by the radial lath be distributed in circumferentially.Percolation region 17 should provide flow surface large as far as possible, gas flow percolation large as far as possible can be made by percolation passage.For this reason advantageously, percolation region 17 is arranged on radially outer on valve element 2.
In guiding area 16, be provided with a central void 18, inner circumferential surface forms the guide surface being used for valve element 2.In order to lead to valve element 2, be provided with the guide finger 4 of central authorities in valve seat 10, this guide finger to extend out and valve element 2 to push away with its central void 18 and installs to the axial end portion freely of this guide finger from valve seat 10 vertically.Therefore valve element 2 can axially movably, with being directed to support on guide finger 4.But guide finger 4 also can be the part of the entirety of valve seat 10.As shown in FIG. 1, in the guide section of guide finger 4, also can load the slip ring 20 be made up of material favourable in tribology, such as PTFE in circumferential groove 19, still to reduce the friction between valve element 2 and guide finger 4 further.Also O shape circle 21 can be loaded, so that tensioning slip ring 20 between the bottom of circumferential groove 19 and slip ring 20.
The end deviating from valve seat 10 of valve element 2 is provided with armature 22, and this armature acts synergistically with electromagnet 5 to open and close air valve 1.Armature 22 is connected with valve element 2 outside the radial direction of guide finger 4, here such as by being distributed in screw circumferentially.But armature 22 also can be a part for valve element 2.But due to the different material requirements of armature 22 and valve element 2, this armature and valve element are configured to two-part usually.
In the embodiment shown in fig. 1, the helical spring 6 be arranged on an end in the space 11 in adjusting element 8 is arranged in baffle ring 23 with relative the other end.The guiding area 16 that baffle ring 23 abuts in valve element 2 vertically is partly arranged around armature 22 and electromagnet 5.Also space washer 24 can be provided with, residual gap (when electromagnet 5 is energized remaining air gap) can be adjusted to desired value between baffle ring 23 and valve element 2.At this, baffle ring 23 (and therefore also having the valve element 2 with armature 22) pushes against the direction of fixing adjusting element 8 towards valve seat 10 and is therefore used from the effect of the closedown spring of air valve 1 by helical spring 6.But helical spring 6 also pushes separated from one another vertically to baffle ring 23 and adjusting element 8, thus produces axial distance x between which, this preset distance Valve travel.By the rotation of adjusting nut 12 in adjusting element 8, this axial distance x (and thus Valve travel) is increased or reduces.Very simply and very accurately can regulate in such a way or regulating valve stroke again, and will not take apart by air valve.
But it is also contemplated that an end of helical spring 6 is set directly in valve element 2, therefore also can save baffle ring 23 and can save space washer 24 if desired.In this case, valve element 2 will directly abut on adjusting element 8 in the open state.But due to high opening speed, produce high gear by power when opening, this gear is by power possibility damage threshold element 2, and therefore baffle ring 23 is preferred.
Valve element 2 is usually made up of firmly material, such as make by metal, as steel, or the plastics strengthened by suitable plastics or fiber are made.
In order to prevent the cold welding between valve seat 10 and valve element 2, also suitable combination of materials can be selected.For this reason, be preferably valve element 2 and valve seat 10 and use different metals, such as valve seat 10 is formed from steel, and valve element 2 by aluminium, the aluminium of particular surface processing example as anodized coating may be had make.But valve element 2 also can with valve seat 10 in combination by metal, the plastics manufacture strengthened by suitable plastics or fiber.
But can expect equally, abandon movable adjusting element 8 and adjusting nut 12.In this case, electromagnet 5 can be arranged in correspondingly configured middleware 9 (it such as can be shaping as middleware 9 is together with adjusting element 8).The adjustment of Valve travel just can such as be carried out between middleware 9 and valve element 2 or baffle ring 23 by different space washers.
The above-mentioned mode of execution of air valve 1 also can realize very simple assembling and the maintenance of air valve, because valve seat 1 can take off very simply and the miscellaneous part of air valve 1 just can be close from that side of valve seat 1.For this reason, such as only must get the next bail wire 29 be fixed on by guide finger 4 in valve seat 10, therefore can take off valve seat 10.But valve seat 10 also can be removed together with guide finger 4 naturally.
Preferably be arranged on the axial end portion of air valve 1 by gas inlet and gas outlet, also the Security of the Leakage prevention improved the structure of the compact double-walled of air valve 1 can be realized very simply, can be guaranteed for the application of sensitivity (such as in ship application).For this reason, the wall around housing 3 can build the second wall 30 simply, and this second wall surrounds air valve 1 (as in FIG shown in the dotted line of side) completely.If be positioned at now inner air valve 1 to become packing less, then outside wall 30 guarantees that gas can not be overflowed from air valve 1.
Under the state be not energized of electromagnet 5, valve element 2 to be pressed against on valve seat 10 via baffle ring 23 by helical spring 2 and therefore seals air valve 1.If give electromagnet 5 be energized, then armature 22 is attracted, therefore valve element 2 from valve seat 10 lift and gas energy percolation by air valve 1.Baffle ring 23 abuts on adjusting element 8 at this under the state opened completely, and therefore this adjusting element forms the blocked part for valve element 2.
Between electromagnet 5 and armature 22, form the first volume 26 that is filled with gas, this first volume such as plays buffer function when valve is opened.In order to air valve 1 can be opened quickly, a space 27 be communicated with larger ventilation volume 28 can be provided with in armature 22, such as axially across the boring of armature 22, described larger ventilation volume such as guide finger 4 and between the axial end portion separated vertically of armature 22.Therefore, when air valve is opened, the first volume 26 ventilates via space 27.
